It will now be seen a part of this specification, myimproved apthat when the hand-wheel is rotated the movparatus is shownconstructed in a form which able jaw will be fed to the right or to theleft adapts the same more especially for repairon the screw-rods 8 8,according to the direc- 50 ing lines of pipe or similar metalstructures; tion of rotation. I can thus adjust the disroo tance of themovable clamp from the .fixed clamp.

The construction so far described is an effective means for clamping anobject to be heated electrically between the two clamps and foradjusting the movable clamp with reference to the stationary clamp withease and comfort; but I am by no means limited to this identicalconstruction, since for the purposes of my invention any other form ofclamp and adjusting devices for the same may be employed.

Each of the two clamps is provided with a binding-post 20, through whichthe heatingcurrent is carried to the clamps and to the object held bythe same by conductors 2l, which, it will be understood, are connectedwith the sou-ree of heating-current. (Not shown in the drawings.) One ofthese bindingposts is shown in the drawings secured to the lower jaw ofthe stationary clamp, Fig. 2, and the other binding-post is shown asconnected with the upper jaw of the movable clamp, Fig. 1, but thesebinding-posts maybe differently placed, so long as provision is made forpassing current through the object held by the clamps between the sameand so long as provision is made against a short circuit around theclamps, which in the construction shown is done by the insulationinterposed between the nut-bearing 17 and the body of the lower jaw ofthe movable clamp and by the insulation 7 on the bearing 7.

The upper jaw 4 of the stationary clamp has formed upon its upper face adovetail guide 22, and into this guide is fitted a slide 23, formed withan undercut groove. This slide 23 is either secured to or formed in onepiece with a rectangular frame 24, so that the whole frame can movelongitudinally upon the upper jaw of the stationary clamp. This movementis effected by a feed-screw 25, having a smooth bearing in a lug 26,formed on the under side of the slide .3, and a nut-bearing in one endof the clamp-jaw et. The projecting end 27 of the feed-screw is squaredfor the application of a crank or hand wheel.

A carriage 28 is mounted in the frame 24, so as to be movable verticallytherein, and this movement is effected bya screw 29, swiveled to thecarriage and having a nut-bearing in the upper end of the frame 24, ahand or crank wheel 30 being used for operating the screw. Thus it ispossible to raise and lower the carriage within the frame. On thiscarriage 28 is mounted an electric motor 3l, (indicated in dotted linesin Fig. 2,) and to the armature-shaft of this motoris secured a pinion32, meshing with a gear 33, iiXed to one end of a shaft 3l, the otherend of which carries a rotary cutting-tool 35, which may be either afusion disk or a circular saw.

Current is admitted to the motor by flexible conductors 36 36, whichcurrent may be taken from the same source which supplies theheating-current for the object held between the clamps, or a separatesource of eur rent may be used.

For the purposes of my invention I need not necessarily use an electricmotor, since any other form of effective motor, whether it be actuatedby steam, air, gas, or water, and whether there be or not areducing-gear, herein shown, may be used. An electric motor, however,has special advantages, on account of ease of manipulation and itscomparatively small weight.

It will now be seen that by operating the screw 29 the carriage 28 maybe lowered until the rotary cutter 35 bears upon, cuts into, andeventually through the object held by the clamps. By operating the screw25, the cutting-tool can be adjusted to the desired position, and byoperating the screw-rods S S the length of the portion of the pipe orrod to be heated is determined. The operation of this apparatus `for thepractice of the methods dcscribed in my aforesaid application and patentwill now be clear.

Suppose it be desired to cut a pipe into two pieces. It is then onlynecessary to clamp it on one side of the line of the proposed cut in thestationary clamp, then adjust the movable clamp by properly operatin gthe hand-wheel 13, then clamp the pipe (marked in the drawings by thenumeral 37) in the movable clamp, then pass a heating-current betweenthe two clamps and through the portion of the pipe extending between thesame, then adjust the cutter 35 by the screw 25 to the requiredposition, an d finally feed the carriage downward until the cut iseffected, it being understood that current has been applied to theelectric motor. If in this manner a defective section of a metalstructure has been cut out, the cut ends may be welded together, or anew section may be welded in between the cut ends by the same machine.It is then only necessary to raise the cutting-tool, bring the ends tobe welded into contact by actuating the hand-wheel 13, pass awelding-current bctween the clamps, and simultaneously therewith forcethese ends together by operating the same hand-wheel until the weld iseffected. The clamps therefore serve the purpose both of electricallyheating a section of a metal structure preparatory to and during theoperation of cutting it and also of welding two pieces togetherelectrically.

Having now fully described my invention, I claim and desire to secure byLetters Patent- 1. An electric metal-working apparatus comprising clampsfor holding the metal to be operated upon and constituting the terminalsof an electric heating-circuit, and an electrically-operatedcutting-tool mounted adjustably with reference to the work andadjustable between the clamps, substantially as described.

2. In an electric metal-working apparatus, the combination of clamps forholding the metal to be operated upon, and constituting IOC IIO

the terminals of an electric heating-circuit; with a frame adjustablymounted upon one of said clamps and an electrically-operated cuttingtool adjust-ably mounted in said frame, substantially as described.

3. In a metal-working apparatus, the combination of clamps constitutingthe terminals of an electric heating-circuit; with ways or guidesextending parallel upon one of said clamps, and a cutting apparatusmounted on said ways or guides, substantially as described.

4. In a metal-working apparatus, the combination of clamps constitutingthe terminals of an electric heating-circuit; with a cutting-toolmounted upon one of said clamps for operation in a plane between theclamps and adjustable longitudinally7 between the same, substantially asdescribed. 5. An electric metal-working apparatus, comprising` twoclamps for holding a section of a metal structure and passing anelectric heating-current through the same, and a cutting apparatusmounted upon one of these clamps in operative relation to the portion ofthe structure which extends between the clamps, substantially asdescribed.

6. In an electric metal-working apparatus, the combination of a fixedand a movable clamp for holding a section of a metal structure and forpassing an electric heating-cur- -and cutting apparatus, the combinationof one iixed and one movable clamp, insulated from each other, and eachconstituting the terminal of a source of electric heating or weldingcurrent; with an electrically-operated rotary cutter mounted upon thefixed clamp, adj ustable longitudinally between the clamps, andtransversely to the line between the same, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
